I have to admit, I wasn't sure what colors I should use, and I don't really have any sets geared to teen boys, so I went with DSP from Well Worn and since we're in Alaska I used the moose image from Definitively Decorative Pines. The text/ sentiments are from the set Bring On the Cake.
Supplies used(all supplies SU unless otherwise noted):
Stamps: Definitively Decorative Pines, Bring On the Cake
Paper: Early Espresso, Very Vanilla, Well Worn DSP, Neutrals DSP, Whisper White for the envelope
